Some networking gear lives in a climate-controlled data center. This isn’t that gear. The ComNet RLGE2FE16R System (RLGE2FE16R/S/48/28/S22/CH+) is built for the places most switches would fail outright — electrical utility substations, switchyards, heavy manufacturing floors, and trackside equipment enclosures where electromagnetic noise and voltage transients are just part of the job.

This configuration pairs 2x SFP uplinks, 8x 10/100 TX Ethernet ports, and 4x RS-232 serial ports with a 36–60 VDC redundant power input — a rock-solid combination for mission-critical SCADA and utility communications. Let’s walk through the specs, see where it fits, and cover how to get pricing.

Why Utilities and Critical Infrastructure Teams Trust It

ComNet’s RLGE2FE16R series are substation-rated and industrially hardened Layer 2 managed switches / Layer 3 routers, purpose-built around a highly robust, SCADA-aware packet-processing security firewall for the most mission-critical, demanding cybersecurity environments. That’s not marketing fluff — it’s the actual engineering premise behind this product line.

Full Data Sheet

Note: The “CH+” suffix on this specific SKU could not be independently confirmed against ComNet’s published ordering codes during research — other variants in this series use suffixes like “CEU” (EU LTE bands), “CNA” (NA LTE bands), and “CGU” (2G/3G GPRS/UMTS). Please confirm the exact cellular/connectivity option for “CH+” directly with ComNet or your distributor before finalizing an order.

Built to Survive Where Others Fail

Here’s a friendly look at why utility and critical-infrastructure teams specifically reach for hardened gear like this instead of standard commercial switches.

Popular Use Cases

Engineered for the Environments Others Avoid

Standard commercial networking gear simply isn’t designed to survive what’s routine in a substation switchyard or a heavy manufacturing plant — high electromagnetic interference, sudden voltage transients, extreme temperature swings, and constant vibration. The RLGE2FE16R series exists specifically to close that gap, combining a rugged metal housing with DIN-rail mounting and IP-30 ingress protection so it holds up in enclosures that would degrade typical commercial switches within months.

The SCADA-aware security firewall is arguably the standout feature here. Rather than treating security as a bolted-on afterthought, this platform is built around packet-processing logic that understands SCADA traffic patterns — layering Layer 2/3/4 ACLs, IPsec VPN support, and IEEE 802.1X port-based access control on top of a firewall designed with critical infrastructure protocols in mind. For utility networks that need to align with NERC-CIP cybersecurity principles, that purpose-built approach matters far more than a generic enterprise firewall bolted onto industrial hardware.

The 4x RS-232 serial gateway and tunneling support also deserves a mention — a huge amount of SCADA and utility equipment still communicates over legacy serial protocols, and this platform lets that equipment ride securely over modern IP-based networks without requiring a costly rip-and-replace of field devices that, in many cases, are decades old and still perfectly functional.

And with dual redundant DC power input, fault/event notification through Syslog and SNMP traps, and Layer 3 routing that lets it participate as a genuine piece of core network infrastructure rather than just an edge switch, the RLGE2FE16R is built for teams who need this hardware to keep working — quietly, reliably, and securely — for years in conditions that would take out less specialized equipment.
